Excerpt from 'The Message':
The representatives: 'Your words do not satisfy us. The best way to resolve the issue is that we should engage in imprecation with each other at an appointed time and may curse the liar and pray to Allah that He may destroy the liar.'
At this moment the Archangel Jibreel came and brought the verse pertaining to imprecation and conveyed to the Prophet the Divine command that he should engage in imprecation with those, who contended and disputed with him and both the parties should pray to Allah that He might deprive the liar of His blessings. The Holy Qur'an says,
'If anyone disputes with you after the knowledge has come to you, say, 'Let each of us bring our children, our women, our people and ourselves to one place and pray to Allah to curse upon the liars among us'.' (Surah Ale Imran, 3:62)
Both the parties agreed to settle the issue through imprecation and it was decided that all of them would be ready for it on the following day.
The time for Mubahilah arrived. The Prophet and members of the deputation of Najran had already agreed that the ceremonies of Mubahilah should take place at a spot outside the city of Madina in the desert. Out of the Muslims and many relatives of his, the Prophet selected only four persons who were to participate in this significant event.
These four persons were Ali bin Abi Talib, Fatimah, daughter of the Prophet, Hasan and Husayn, as amongst all the Muslims no purer souls could be found. He covered the distance between his house and the place fixed for Mubahilah in a special manner. He stepped into the field of Mubahilah when he was carrying Husayn in his lap, and was holding the hand of Hasan in his own hand, and Fatimah was following him and Ali bin Abi Talib was walking behind them.
Before arriving at the place fixed for Mubahilah he said to his companions: 'Whenever I utter an invocation you should pray for its acceptance by saying Amin.'
Before facing the Prophet the chiefs of the representatives of Najran were saying to one another: 'In case you see that Muhammad has brought his warriors and officers in the field of Mubahilah and has displayed his material grandeur and external strength you should conclude that his claim is not true and he has no faith in his prophethood.
If, however, he comes for Mubahilah along with his children and the dearest ones and appears before the Almighty Allah devoid of every sort of material might and glory, it would mean that he is a true Prophet and has so much faith and self-reliance that he is not only ready to be annihilated personally, but is fully prepared with perfect courage to let his dearest ones also meet destruction and extinction.'
While the chiefs of the deputation were engaged in conversation, the Prophet made a sudden appearance before the Christians of Najran along with four of his dear ones, out of whom three were his own offspring. All were wonder-struck to see that he had brought into the field of Mubahilah even the innocent children of his dear daughter and said: 'This man has perfect faith in his call and claim, because a wavering person does not bring his dearest ones into the arena of Divine wrath.'
The Bishop of Najran said: 'I see such faces that if they raise their hands in supplication and pray to Allah that the biggest mountain may be moved from its place, the same will happen immediately. We should in no circumstances engage in Mubahilah with these sacred and virtuous personalities because it is not improbable that we may be annihilated and it is also possible that the Divine wrath may expand and engulf the entire Christian world and not even one Christian may remain alive on the face of the earth!'
